## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability is-downdetector-com-down-25e7012a
```

Example prompt: Can you check if downdetector.com is actually down right now or if it's just a problem on my end?

## When to prefer this

Use this endpoint when a user or agent specifically reports that downdetector.com is inaccessible and you need to distinguish a real outage from a local network problem. Prefer it over general uptime services when you need an edge-based check with TLS validation included in a single $0.01 call.

## Known failure modes

- downdetector.com itself may be slow to respond, causing a timeout in the check
- TLS certificate issues on downdetector.com will be flagged as invalid but the check itself still completes
- Cloudflare edge network issues could produce a false-positive down result
- Payment failure (insufficient USDC balance) will prevent the check from running

## How this service works

Is downdetector.com down right now? Live check from Cloudflare's edge: HTTP status, response time, final URL after redirects, server header and whether the TLS certificate is valid, with an up/down verdict. Call it when a user or agent says "downdetector.com isn't loading" to tell a real outage from a local problem. $0.01 per check.

## Output

Returns an up/down verdict for downdetector.com along with the HTTP status code, response time in milliseconds, final URL after any redirects, the server header value, and whether the TLS certificate is currently valid — all measured from Cloudflare's edge network.
